' I comsrnucrrcnor rim-cerium Application filed February To. all whom itmay conbern: J Be it known that I,'HARRY ZWICK, a citi- .zen of theUnited States, and a resident of the borough of'Brooklyn, in the countyof Kings, city and State of New Yoi'k, have mvented -certain new anduseful Improvements in the Construction ofFile-Cabinet Drawers, of whichthe following is a specifi- I an end portion of a box made from thecation. I

My improvements relate to, the manufac- 'ture of boxes out ofcard-board, so called, covering the various grades thereof as known tothe trade, or out of any analogous fibrous board material 5 andparticularly to the making of rectangular boxes out of onepiece bodyblanks, the upsettingor folding appearance, and also ehdanger theintegrity of the portions of the wrap spanning and covering these cornergrooves, which ob viously afford no support for the overlapping portionof the wrap.

The .main object is to obviate this difiiculty, in so far at least asthe ends of the boxare concerned, and to-afiord a flush rec- H tangularfinish thereto, of the-=full .width of the box, whereby the bevel-edgeeffect is eliminated; a true rectangular corner effect is produced;andthe wrap is supported against extraneous pressure;and whereby, also,If-

simplify and cheapen the cost of production,

' and reinforce and strengthen the box structure' in a unitary sense,all as hereinafter more fully set forth. To-this end theinventionconsists in the specific construction and arrangement of arts describedand claimed, adistinctive eature being the use of auxiliary end plates,of full box width and-height, which overla the end edge groovesincidental to the fo ding or setting up of the body blank, as hereinshown and described. I

My construction resultsin a s onger box, better adapted to withstand t 0require- I ents, of use,than when the box is formed in the, older,methods. I j

In the accompanyin drawings I exemplify a'p'ractical embo iment of minvention as applied-to a box of the in ex cabinet drawer type, althoughI do not limit' mys'e1f to this or any particular type of rec- 17, 1923.Serial No. 619358.

which are scored on the under side of'the blank to facilitate thebending of themate- .rial as preseribed, results in the formation. ofexterior angle grooves g', g, which are eventually covered and closed bythe wrap w. But the corner finish thus attained is.

bevel-shaped or chamfered, as shown more gprticularly at z, in Figs. 5and 8 of the awings. This is especially objectionable at the endcprners, not onl on account of 'alppearancefbut' more particularlybecause t e an ar grooves g, g, is .un -su'ported, so thatslightextraneouspressure a o ng these rtion of the wrap w, covering said.

. lines of angular band is apt to rupture the wrap and create a raggedappearance, at the same time exposing the end edges of the side members;s, s, of the box body for contact with, say, the edges of the drawer.space in thecabinet to which the box belongs, or

with other extraneous objects. Furtherit more, this vulnerability of theend corners of the box or drawer detract from the strength, utility, anddurability of the whole structure.

By my provision of independent auxiliary V c'ircumscri'bing end boardsa, a, I am enabled .to so form the end folds e, e, in such manner thatthey restupon the floor or bottom member I), flush with the end edgethereof,

as will be understood "by reference particularly to Figs. 10 and 11, ofdrawings,-the

spaces 0., 0, representing the socketsfor the ends of thelon'gitudinalcard rests 0', 0', usually providedin index boxes or drawers of thecharacter designated,'and d, d, being' the socket holes for the ends ofthe usual card rod d',these latter features being only incidental to theindex box or tray herein'used as an illustration of a practicalembodiment of my invention; the essential feature of whichis theprovision'of the independent eircumscribing end boards, a, a, of thefull exterior. area of the box in cross section, as illustrated in Figs;2, 3, 4 and 6 of thedrawings. P

These independent full dimension end boards a, a, not'only isolate andprotect the side end grooves, g, 9, but they are especially eficaciousin connection with the end structure of; box body shown. inFig.'11,since they are pasted, not only to the flaps e, 9, but also-tothe end edges of the box bottom 6, thereby insuring. strengthandintegrity of box structure, considered in a, unitary Anotherpractical advantage attained by my independent full dimension end boar santeater a, a, is that they maybe passed through a pasting machinepreparatory to attachment to the end over-laps and bottom $11" the boxfbody, thereby dispensing with h d pasting in this respect, and greatlyfacilitating the rectangular endcorpers, together with reinforced endconstruction.
